Peer review isn't perfect, but it's supposed to filter out papers with obvious and major flaws.
And usually scientific journals which are more highly regarded, are supposed to be more strict in their peer review process than others. Which is how they become highly regarded in the first place.
The hydroxychloroquine paper for example had major flaws in the design of the analysis. There wasn't even a need for an expert in order to discover that, and you're supposed to have experts doing the peer review process in such a highly regarded journal.
So Palestinians are Hamas?
Why is Iran not helping Fatah?
Their support of Hamas is on ideological grounds. Israel is holy waqf land that belongs to Muslims and should be cleansed from Jews.
Even when Egypt had sovereignty over Gaza they made sure to prevent Palestinians from going to Egypt.
Tunnels from Lebanon... to Gaza..? Where'd you read that?
Hezbollah begun bombing Israel in support of Hamas. They're also funded by Iran (much more than Hamas though).
Meanwhile Palestinians live in camps in Lebanon. Some of those walled and surrounded by watchtowers.
They have less rights there than anyone else (including refugees and migrant workers), despite living there for 3 generations at this point.
Turkey under Erdogan has been mostly hosting Hamas leaders while bombing Kurds in Syria.
I don't think much needs to be said about Assad.
The only country in the area which actually helped Palestinians was Jordan. Although that also changed for a while after Black September.
Most of UNRWA's funding over the years has come from the EU and USA.
